This is a 12 bolt with 4:56 gears. I recently acquired this and figured it would be better than my stock 10 bolt. I am new to lockers and my guess is that this is a gov lock. Also does it look the way it is supposed to? Thanks

Guess the locker???? Does it look right?

Depends on what you need it for as to whether it's "better" than your previous ten bolt.
I split the carrier in the 10 bolt on the street with 33's and 3.42 gears, and that's the gov-locks weakness, the carrier. Open diff 10 bolt would probably holdup a long time where a gov-locked one won't.

I would most definitely NOT drive on that , you are missing a part in the lower of the pic that goes on the pin going from right to left .
You are one step away from walking home with chunks of metal in your pocket .
If the gears look OK , get an open carrier .

Looky , you have no latching bracket 
I was just looking for a diagram ;-) Thanks a lot. The latching pin is circled in this pic. Looking at the diagram the other pin should be the stop pin. Thanks again! Sorry my pic is not very clear. Should have used the macro on my camera.
I don't *think* that will be a problem, except for what happened to that piece to A) remove it from the carrier and B) what all the pieces went through when it did come off.
If there is no damage on ANY of the gears, I wouldn't worry about it. It will simply not be a locking differential anymore (which is why they are weak) it will "fail" as an open diff. Of course, no telling what the bearings and races look like, but run it till it breaks if you paid for it and can't get your money back.
Hard to tell from the pic quality, if it's there, it's ok then.

Its definitely not there , both the governor and latching bracket should be right there to see with the naked eye . It should be on that pin and you could move it a little bit with your finger .
Yeah, to me that whole thing looks a bit different than the 10 bolt version, but I have no idea if they are SUPPOSED to look identical.
